82 Mr. C. 0. Waterhouse on Madagascar Cetoniidae. 



Coptomia Icevis. 



La)te viridi-prasina, omnino laevis ; tibiis tarsisque obscure rufis, 



illis rcneo tinctis. <J . 

 Long. 11^- Iin. 



The largest species of this group at present known to me. 

 Uniform shining grass-green, without any punctuation above 

 or on the pygidium, except a few punctures between the eyes. 

 The sides of the metasternum are sparingly punctured. The 

 propygidium is strigose. 



The only species which this resembles is Coptomia muta- 

 bilis, W. (Ann. & Mag. Nat. Hist. 1878, ii. p. 139), from 

 which it differs in being of a more elegant and elongate form, 

 in the longer legs and tarsi, in the absence of the strigosity 

 on the subapical callosity of the elytra, and in having no 

 punctures on the pygidium. The sternal process is more 

 slender. 



Coptomia uniformis. 



Castanea, viridi tincta, nitidissima ; capite thoraccque olivaceis, 

 cupreo tiuctis ; elytris pallidc olivaceis ; tibiis tarsisque rufo- 

 piceis. 6 2 • 



Long. 9-10 lin. 



Very close to C. mutabilis, but less bright green, more 

 castaneous below, of a narrower form, and with the sternal 

 process much more porrect. Pale olive-green above, the 

 head and thorax more generally showing a castaneous or 

 coppery tinge. The head moderately thickly punctured be- 

 tween the eyes. Thorax smooth. Elytra with very ob- 

 scurely punctured lightly impressed lines ; the side of the 

 apical callosity and the apex rather closely strigose. The 

 pygidium with distinct punctures scattered over the sur- 

 face. 



Coptomia crucigera. 



Nigra, nitida ; thorace, elytris, pedibus pygidioque apice rufo- 

 ochraceis ; thorace vitta mediana lata et elytrorum sutura fas- 

 ciaque nigris. $ 5 . 



Most nearly allied to C. nigriceps, W., but quite distinct 

 by its coloration from all known species. The black on the 

 suture of the elytra is narrow, but dilates towards the base 

 and surrounds the scutellum ; the transverse mesial fascia is 

 broad. The pygidium is very densely and extremely finely 

 strigose. The anterior tibia? are a little more slender than in 

 the female, and the three teeth are less strong; the abdominal 

 impression is very slight.
